Title:
NON-AQUEOUS ELECTROLYTIC SOLUTION AND ENERGY DEVICE USING THE SAME
Document Type and Number:
Japanese Patent JP2023130374
Kind Code:
A
Abstract:
To provide a non-aqueous electrolytic solution secondary battery that has improved input/output characteristics and has solved problems of the capacity in an endurance test including cycle characteristics and storage characteristics, battery swelling, positive electrode metal elution, and safety.SOLUTION: A non-aqueous electrolytic solution contains one or more compounds selected from a group (A) consisting of a compound represented by X-SO2-Y-SO2-Z (1) [Y is an organic group including one of a nitrogen atom and a carbon atom. X and Z are a hydrocarbon group that may contain a fluorine atom having 1-12 carbon atoms or a fluorine atom. n is an integer of 1 or more and 2 or less.] and a cyclic compound having a SO3 structure, and a fluorosulfonic acid salt (B) represented by (FSO3)xM (2). [M is a metal atom, and x is the valence of the metal atom M and an integer of 1 or more.] The ratio of the content mass of the fluorosulfonic acid salt (B) to the content mass of the compound belonging to the group (A) is 1 or less. The content of the compound belonging to the group (A) is 0.01 mass% or more and 8 mass% or less.SELECTED DRAWING: None
